Contact bonding with heat reactivation
Also: heat activation, reactivating
In contact bonding, the glue dries on both surfaces and is then reactivated with heat. Only then do the parts stick.
The advantage: you can still align the parts before heating. The Anfibio blog gives about 90 °C for loops and 60 °C in the fin guide, each heated section by section with a hair dryer and pressed firmly. A small seam roller or the back of a spoon helps push out air bubbles.
